• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

S1 belly tank - bungee gear

Hi everyone,

Finishing the wings on the S1SS I'll soon start working on the fuselage (truss already completed).
In order to minimize acro weight, I opted for no upper wing tank, but am considering a removable ferry belly tank alas Su26.

I know the topic has been discussed here before (lots of interesting stuff about it), but it seems to have only been done on Pitts S1 with spring gear, as if not applicable to the bungee...
Mine has bungee gear and I can't see why it couldn't be done... Am I missing something ? Or even better has it been done already on a bungee S1 and someone has the pics ?

Cheers !
